CAUTION
RISK OF ELECTRIC SHOCK. Prior to starting the wiring procedure, ensure
that the three-pole circuit breaker is switched off and are LOTO.
NOTE
Damage or destruction of the inverter's electronic components due to
moisture and dust intrusion will occur if the enclosure opening is enlarged.
CAUTION
Risk of fire if two conductors are connected to one terminal. If a
connection of two conductors to a terminal is made, a fire can occur.
NEVER CONNECT MORE THAN ONE CONDUCTOR PER TERMINAL.
NOTE
Use M10 crimp terminals to connect to the inverter AC terminals.

All electrical installations must be carried out in accordance with the local standards and
the National Electrical Code® ANSI/NFPA 70 or the Canadian Electrical Code® CSA C22.1.
The AC and DC electric circuits are isolated from the enclosure. If required by section 250
of the National Electrical Code®, ANSI/NFPA 70, the installer is responsible for grounding
the system.
The grid voltage must be within the permissible range. The exact operating range of the
inverter is specified in Section 9 “Specifications”.
